Overview of Insulation Materials: Quick Book
ISBN: 9781505411607 / Angielski / Miękka / 2014 / 78 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) Prevention of heat loss by application of insulation is the simplest method of achieving substantial economies in energy. Some estimates have predicted that insulation in US industry alone saves approximately 200 million barrels of oil every year. The other benefits include the improved productivity, enhanced environmental quality, personal safety, process control, reduction in noise levels and also the fire safety. The most important characteristics of an insulation material is low thermal conductivity, low tendency toward absorbing water, and of course the material should be inexpensive....

Heat Rejection Options in HVAC Systems: Quick Book
ISBN: 9781505381672 / Angielski / Miękka / 2014 / 70 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) One of the basic requirements of the air conditioning and refrigeration system is to reject heat to the outdoors. The refrigerant chillers come in two different forms: An air-cooled chiller uses the flow of outside air across the condenser to remove or reject heat from the chiller. Air-cooled chillers typically have the condenser mounted on the roof or somewhere outside the facility while the evaporator can either be inside or outside the facility. Water-cooled chillers are typically 100 tons or greater and use water to remove the heat from the condenser. Water-cooled chillers are typically...

20 Ways to Optimize Efficiency in the Use of Induction Motors: Quick Book
ISBN: 9781508586296 / Angielski / Miękka / 2015 / 86 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) The majority of electrical energy consumed in most industrial facilities is used to run electric motors. Annual energy operating costs of electric motors usually far exceed purchase prices. For example, a typical 25 horsepower (hp) motor running at full load for 6,000 hours per year would consume nearly $10,000 of electricity annually. An average purchase price for a motor of this size would be only $500 to $600. Energy efficiency decisions are important decisions that affect operating cost for the life of the equipment. By optimizing the efficiency of your motor-driven systems, you can...

Circuit Control Devices: Quick Book
ISBN: 9781508516934 / Angielski / Miękka / 2015 / 40 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) Circuit control in its simplest form, is the application and removal of power. This can also be expressed as turning a circuit on and off or opening and closing a circuit. Before you learn about the application of circuit control devices, you should know why circuit control is needed. If a circuit develops problems that could damage the equipment or endanger personnel, it should be possible to remove the power from that circuit. The circuit protection devices (fuses and breakers) are not the control devices; these are protection devices that will remove power automatically in event of...

Design Considerations for Hot Water Plumbing: Quick Book
ISBN: 9781502853134 / Angielski / Miękka / 2014 / 104 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) Heating water is typically the second largest use of energy in residential and commercial buildings (after space heating and cooling). Despite its resource intensity, the hot water delivery system is seldom an area of significant focus when constructing a building. As a result, many buildings today are built with poor performing, inefficient hot water delivery systems that take minutes to deliver hot water to the point of use and waste large amounts of energy and water in the process. How quickly and efficiently a hot water system can deliver to the point of use require focus on three areas:...

HVAC - Variable Refrigerant Flow (VRF) Systems: Quick Book
ISBN: 9781505394047 / Angielski / Miękka / 2014 / 46 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) VRF (Variable refrigerant flow) is an air-condition system configuration where there is one outdoor condensing unit and multiple indoor units. The term variable refrigerant flow (VRF) refers to the ability of the system to control the amount of refrigerant flowing to the multiple evaporators (indoor units), enabling the use of many evaporators of differing capacities and configurations connected to single condensing unit. The arrangement provides an individualized comfort control, and simultaneous heating and cooling in different zones. Currently widely applied in large buildings especially...

HVAC Instrumentation and Control: Quick Book
ISBN: 9781505294156 / Angielski / Miękka / 2014 / 136 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) The HVAC systems are designed for peak conditions. Because these conditions prevail only for small period in a year, the HVAC equipment must operate most of the time at lean capacity. The function of the control system is to adjust the equipment capacity to match the load. Automatic controls are necessary not only to achieve the design conditions in the conditioned space but are also required for efficient operation of the HVAC system. The main parameters to be controlled in air conditioning system are temperature, pressure, humidity, air quality and thermal energy distribution. This 6 -hour...

ISBN: 9781502848635 / Angielski / Miękka / 2014 / 80 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) Temperature is a principle parameter that needs to be monitored and controlled in most engineering applications such as heating, cooling, drying and storage. Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic be it a thermal expansion, thermoelectricity, electrical resistance or thermal radiation. There are four basic types of temperature measuring devices, each working on a different principle: 1.Mechanical (liquid-in-glass thermometers, bimetallic strips, bulb & capillary, pressure type etc.)...

Direct Current Generators: Quick Book
ISBN: 9781508497028 / Angielski / Miękka / 2015 / 52 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) A direct current generator, or DC generator, produces a voltage of constant polarity, which means the voltage and current do not change over time. DC generators are basically AC generators whose output voltage is switched the other way round at the proper moment, so that the direction of the voltage is always in a single direction. The AC generator uses slip rings to transfer the current to the electrical circuit, while the DC generator uses a split-ring commutator. Generators can be very small or quite huge. Commercial DC generators are commonly found in traction applications like subways...

Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) The heating, ventilation and air conditioning (HVAC) systems can be the notorious contributors to nuisance noise in buildings. The HVAC systems and their components must be designed, installed and operated in such a way that any noise they may cause inside the building or neighboring buildings are at levels that do not cause any serious discomfort to the occupants. Noise control is not an exact science; however there are numerous ways the noise can be reduced from a particular source. The most desirable way to control excessive noise levels is by using engineering controls such as application...
